    Abstract: A bipolar electro-surgical instrument (10) has opposable seal surfaces (18, 19) on its jaws (16, 17) for grasping, sealing vessels, and vascular tissue. Inner, and outer instrument members (11, 12) allow arcuate motion of the seal surfaces. An open lock box (13) provides a pivot with a lateral support to maintain alignment of the lateral surfaces. Ratchets (25, 26) on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion (14, 15) on each member is tuned to provide an appropriate spring force to hold the surfaces together. During surgery the instrument can be used to grasp, clamp vascular tissue, and apply bipolar electro-surgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.

    Abstract: Electrosurgical energy is used in combination with a surgical tool (12) to seal vessels and vascular tissue of a patient (13). One of the important advances of the present system is that is can effectively seal vessels of a patient (13) without leaving any foreign material in the body of the patient (13). The present system is also capable of sealing vessels as large as ten millimeters in diameter. Another advantage of the present system is that the surgeon can visually inspect the integrity of the seal. The invention works with a combination of pressure and controlled application of electrosurgical energy to achieve the desired result. A surgical tool (12) is used to grasp and apply an appropriate amount of closure force to the tissue of the patient (13). The tool is capable of conducting electrosurgical energy to the tissue concurrently with the application of the closure force. A method for sealing vessels and vascular tissue of a patient (13) includes the steps of applying pressure to the vessels and other tissues of the patient (13); applying a first level of electrosurgical power to the vessels and other tissues sufficient to melt proteins in the tissue; applying a second level of electrosurgical power to the vessels and other tissues sufficient to cause desiccation without charring; reducing the electrosurgical power substantially to zero for a length of time sufficient to allow the vessels and other tissues to cool into a new compressed form; and relieving the pressure on the tissue.

    Abstract: Se utiliza energía electro-quirurgica en combinacion con un util quirurgico para cerrar los vasos y el tejido vascular de un paciente; uno de los avances importantes del presente sistema consiste en que puede cerrar de manera eficaz los vasos de un paciente sin dejar ningun material extraño en el cuerpo del paciente; el presente sistema está capacitado también para cerrar vasos tan grandes como de diez milímetros de diámetro; otra ventaja del presente sistema consiste en que el cirujano puede inspeccionar visualmente la integridad del cierre; la invencion trabaja con una combinacion de presion y aplicacion controlada de energía electroquirurgica para conseguir el resultado deseado, se utiliza un util quirurgico para coger y aplicar una cantidad apropiada de fuerza de cierre al tejido del paciente; el util está capacitado para conducir energía electro-quirurgica hasta el tejido de manera coincidente con la aplicacion de la fuerza de cierre; un método para cerrar los vasos y el tejido vascular de un paciente incluye las etapas de aplicar presion a los vasos y a los otros tejidos del paciente; aplicar un primer nivel de energía electro-quirurgica a los vasos y al otro tejido suficiente para fundir las proteínas del tejido; aplicar un segundo nivel de energía electro-quirurgica a los vasos y al otro tejido suficiente para provocar la desecacion sin chamuscado; reducir la energía electro-quirurgica sustancialmente a cero durante un periodo de tiempo suficiente para permitir que los vasos y los otros tejidos se enfríen con una nueva forma comprimida, y eliminar la presion del tejido.
